BP 14: Focus: Phase Separation in Biological Systems II (joint session BP/CPP)
Dienstag, 17. März 2020, 09:30–12:45, ZEU 250
Stem cells have the remarkable capacity to differentiate into multiple cell types and therefore play pivotal roles in our understanding of tissue maintenance and disease. Theoretical and experimental approaches from physics have advanced our understanding of stem cell dynamics, while at the same time stem cell biology has led to questions at the frontier of non-equilibrium physics. In this session, we will show how mechanical signalling influences cell fate and how concepts from physics can yield understanding of the collective phenomena underlying stem cell behaviour on the molecular and cellular scales.
